Do mosquito repellent expire? Some of my friends will be out camping this weekend, and they want to know if their mosquito repellent will expire before their trip is over. They are on the fence about bringing mosquito repellent in the first place, so I need to find information that supports the idea of bringing it and switching it out every few days, versus how long it lasts. Have you ever wondered how long mosquito repellent lasts after opening it? You’re not alone. It can be challenging to tell how long mosquito repellent will last without knowing the expiration date. I’ve created a list of 7 things that need to be figured out if you want to know when mosquito repellent expires. Mosquito repellent “expire”? They’re chemicals so I’m sure of it, right? Not exactly. The active ingredients in most mosquito repellents degrade with exposure to sunlight, moisture and air over time, meaning when the package says that their product lasts for up to 10 years, this is an ideal situation where you store it in a cool, dark place and always use fresh sprays. It’s the summertime and that means that there are going to be more and more mosquitos around. While they can be a nuisance, they also carry some serious diseases. Mosquito repellent is an important tool to protect yourself from mosquitos. However, I was wondering if mosquito repellent expires? After all, we don’t want to be using expired medicine in order to avoid contracting diseases. That being said, let’s check out if mosquito repellent expires.
Do Mosquito Repellent Expire
Introduction
On a recent camping trip, I found myself surrounded by mosquito bites. I did a quick review of my first aid kit and realized that my bug repellents were expired! To make sure this doesn’t happen to you, let’s see if do repellents expire, how long they last for, and what happens when they’re past their expiration date.
Do Mosquito Repellent Expire
The short answer is yes. They do expire, and if you’re not sure about how long your repellents last, it’s best to just toss them out anyway.
The long answer: All mosquito repellent products have expiration dates printed on the back of their packaging. While the length of time that they’ll last depends on the type of product—sprays tend to expire sooner than lotions or gels—it’s always better to err on the side of caution and toss any expired spray cans out for good measure.
The even longer answer: Some people choose natural insect repellents like citronella candles or plant-based oils as alternatives to traditional store-bought sprays with DEET (N, N-diethyl-meta-toluamide), but these also have an expiration date printed directly onto them as well (in this case “best used before” or “best by”). Again, just because something is natural doesn’t mean it won’t spoil eventually; if you can’t remember when you bought it but there is still some liquid left in a bottle after three years’ time has passed since opening then throw away anything that seems doubtful while keeping everything else stored safely until next summertime when mosquitoes are at their worst again!
Short answer is yes they do.
Yes, they do. The short answer is that most repellents have an expiration date stamped on them. This means don’t use them after that date because they won’t work as well or at all.
Most sprays and lotions will tend to lose their effectiveness after two to three years, but gels and candles can last for most of a decade if sealed correctly.
The fine print on the back of a repellent product will tell you how long it’s good for and most products have an expiration date stamped on them.
The fine print on the back of a repellent product will tell you how long it’s good for and most products have an expiration date stamped on them. But once you’ve opened it, how long will it keep working?
The effective life of a mosquito repellent differs by type. Some are more time sensitive than others. Mosquito gels and candles can last for most of a decade if sealed correctly. This is because they contain pyrethrins, which degrade rapidly when exposed to air or sunlight (like in their original packaging). Other sprays may lose effectiveness in two or three years—but still provide some protection against mosquitoes during this period.

If you decide to use an older spray, make sure that it’s at least six months old before opening it up. If the container is damaged or leaking, toss it out immediately—it probably won’t work anymore anyway.
If you’re not sure about your repellents, throw them out.
- If it smells bad, it’s probably bad.
- If it has a strange color, it’s probably bad.
- If it doesn’t work, it’s probably bad.
- If it’s not in a sealed container, it’s probably bad.
